Items confiscated from James ‘Whitey’ Bulger’s apartment in Santa Monica, CA when he was found by the FBI in 2011 are going up for auction this week. The items for sale include a gold and diamond Claddagh ring, with a listing price starting at $11,370.

The money raised from the auction, held at the Boston Convention and Exhibition Center on June 25, will go to the families of the former Boston mob boss’s murder victims, the Daily Mail reports.

Also up for sale is a replica Stanley Cup ring, starting at $350; a sterling silver ‘Psycho Killer Ring,’ worth $65, and a total of 67 watches, including a Patek Philippe timepiece listed at $7,350 and 33 Rolexes, according to the US Marshals Service.

Other items up for auction include unworn Asics sneakers, a pack of cushioned insoles, a boxing mannequin wearing a sun hat, clothing, kitchen items, and 30 rolls of paper towels.

The auction will raise money for the families of the 11 people he was convicted of murdering or ordering to have killed in the 1970s and 80s when he was in charge of Boston’s ‘Winter Hill’ gang.

Bulger, now 86, fled Boston in 1994 on a tip from a corrupt FBI agent. He spent 16 years on the run with girlfriend Catherine Greig, now 65, before the FBI caught up with them at their hide-out in Santa Monica.

Johnny Depp portrayed the notorious gangster in Scott Cooper’s "Black Mass," which was released in 2015. Bulger has reportedly said he is not a fan of the film.

The auction will also feature forfeited items from other criminals, including a platinum Audemars Piguet Millenary Maserati MC12 Tourbillon Chronograph limited edition men's watch, with bids starting at $140,000.
